Baroness Scotland of Asthal: The bases for the advice that wider conclusions could not be drawn from the study of nutritional supplements at HMYOI Aylesbury were that:
	The research took place in one prison; it is therefore not possible to demonstrate that findings from this study can be generalised to other environments.
	The study used adjudications in prison as the outcome measure; therefore it is not possible to demonstrate that the findings from this study can be generalised to other behaviours.
	The results, for a sample of 172 young adult prisoners, was a reduction in adjudications of 35 per cent. for those taking the active supplements. Statistically, however, this produces a wide range of possible reductions—from 16 per cent. to 54 per cent. A larger sample size would allow us to be more precise about the impact of the supplements.
